Lung lavage using diluted surfactant has recently been shown to be an alternative to bolus therapy in treating MAS. This has advantage of removing surfactant inhibitors from alveolar space, in addition to augmenting surfactant concentration in alveolar space. Initial pilot case series using surfactant lung lavage have shown promise and there is a need to systematically study this in a RCT. The same has also been expressed in the literature on this subject. Hence the purpose of this prospective randomized controlled trial is to compare the efficacy of surfactant lung lavage over standard therapy in the treatment of meconium aspiration syndrome.
